not sure if serious, but nicely played.
If you have a post that seems to fit, don't try to change the seat tube just based on someone's number on the internet somewhere.
But it's very possible that your seat lug has gotten distorted over the years by abuse and wrongly fitted seat posts. If that's the case, (and you can confirm by taking your caliper and taking a number of measurements of the clamp diameter at different points around the circumference...a distorted seat lug will show up as different diameter measurements), the proper remedy is reaming with an adjustable reamer. Pounding a seat post in with a hammer will only give you the additional issue of a stuck post.
